I think the Marie going off on Heisenburg in Walt's house may be correct... I can also see Jr. finding out and losing his cool and doing the same (maybe on a blue meth rampage).
I don't see Hank dying yet, though perhaps seriously injured (mentally or physically) again, and in trouble at the hospital (Marie's motivation to eff up Walt's place). Gomez is likely a goner, which could also preclude Hank losing his mind and thrashing Walt's house (he has PTSD already, and could go off the deep end with Gomez being killed, or again his going off the deep end could inspire Marie). I also agree that Jesse will somehow end up in a one on one situation with Todd, and he'll either kill him, or Walt will kill him to save Jessie (Todd dying the simple minded "can't believe Walt killed me" way, though I don't think it'll happen yet since I'm certain there will be some more Todd/Lydia awkwardness before the end of the series, (which figures to also play a prominent role in the end of the story since it's still being set up this close to the end). I'm fairly certain that Lydia is going to get the Ricin, and we'll get to watch her end come with all the paranoia coming to fruition.
I think this last episode may have been the turning point where Walt finally realizes all the bad he's brought to the family and now needs to let everything else go to save them, but I imagine he'll either be facing Todd's uncle, or maybe even the chzech gang, not the DEA. He'll go out in a blaze of glory, either from his greed, or from saving his family/Hank/or most likely, Jesse.
Now that Todd's uncle knows about Andrea and Brock, I can see them capturing Jesse and using them to force Jesse to do the cooks (though Lydia figures to be the one to provide the idea behind Jesse's new found meth cooking motivation).
Something will end poorly for someone besides Walt. It could very well be Todd shooting Jesse and Walt then killing Todd. Interestingly enough, I can see Jesse complete his Breaking "Good" hopefully limping away to a new life at the end, Walt finally reversing course after this episode, and Hank actually being so consumed by Gomez's death, (something happening to Marie) that he actually breaks bad at the end in his attempt to get Walt by any means necessary (comment about Pinkman getting killed on tape two episodes ago precludes this IMO).
The ultimate ending has Hank going to kill Jesse in a rage, Walt stepping in front and taking the bullet, dying as Hank collapses in his ultimate horror of his insanity, and Walt asking Hank to let Jesse go in his dying breaths... This is my favorite for the ultimate outcome...
The only other conclusion I can see is super dark... Walt losing everyone, JR on meth to deal with his father's reality,(at some point his character has to show Walt the true consequences of Walt's last 2 years) Skyler in a mental institution/suicide/jail, the baby hopefully in Marie's hands (hard to kill/harm the baby, might be the only positive, but could easily be shown being adopted by new parents completely unrelated to the show at the end if Marie totally loses it). Hank likely dead by Walt's hand in a rage after Hank kills Jesse, Gomez dead already to set off the events leaving Walt completely alone, dying from his cancer alone next to his barrels of money and photos of his family... In some respects, this could show the true horror of what can happen... Life outside of the blue meth circle will go on, but inside, it'll be complete devastation, the worst case scenario on all fronts.
We'll know in a few short weeks...
And regarding, "Personally, I think Walt is pretty cowardly. Very rarely has he killed in cold blood in the series (just the drug dealers he ran over)."
That just seems like a strange comment. I would think seeing that Walt doesn't want to kill would be a positive.
Ted gets out of the hospital only to misjudge the jump into Skylar's bed and breaks the rest of his neck.
(Oh.... You forgot about Ted? Huge loose end).
After reading all the posts from the last couple days, I have somewhat of a new theory..... In the shootout, I think that Walt, Hank, Todd, Jesse and Jack are the only survivors. Hank surrenders and is taken by Jack and Todd, along with Jesse, to some place where they are tied up. Todd and Jack plan to kill Hank and Jesse, but Walt saves them. Walt dies somehow at some point before the end, so Hank does not tell anyone in the DEA about Walt being Heisenberg. Hank tells the DEA he is retiring, and they believe it is due to stress, but really it is because Hank returns to the desert and finds Walt's money. He takes a nice amount of it, gives a bunch to Skylar (for the kids), and gives some to the wife of Gomez. But what happens to Jesse? I think when Walt takes out Jack, and gets Jesse and Hank free and Jesse kills Todd. Hank lets Jesse go, and he disappears and starts a new life..... And on a not so serious note... if it plays out this way, it would be funny if Marie takes all the money from Hank and leaves with Jesse!!
After Walt kills everyone that is a threat to him, he calls Skylar and tells her once again "I won". Then he proceeds to get run over by a bus. Show over/
I'm kind of wondering this... the pic that Jesse sent to Walt. Where did they get the pile of cash to put in that barrel? Not that it is significant or anything, but was just curious about that.
They had Jesse's pile of cash. When Jesse got into Hank's Durango at Walt house, Hank put the orange duffel bag with Jesse's cash in the front seat.
